Definitions

  • This application contemplates generally a proc-ess of helically winding a filament or a plurality of filaments onto a mandrel or form in the presence of a suitable binder.
  • the most dynamic aspect of the filament winding process has been in the field of glass fiber reinforced vessels, wherein the filament includes a number of glass fibers and the matrix or binder is one of the conventional plastics such as a polyester or epoxy resin.
  • the solidified binder gives form and a certain degree of rigidity to the resulting vessels; but it is the filament, in this case glass fiber which reinforces and greatly increases the tensile strength of the vessel.
  • the manufacture of a given vessel by the filament winding process requires a mandrel or form of the exact dimensions desired in the finished vessel, over which the filament may be wound.
  • the feeding mechanism which must traverse the full length of the product being made, and which must be so synchronized with the pay out speed of the filament that a proper helix angle will be achieved, must be variable so that a normal range of products, sizes and shapes may be accommodated.
  • This yfurther requires that the means for releasing the finished vessel from the forms must also be adjustable.
  • the temperature conditions over the entire form must be carefully controlled in order to achieve a proper soliditication of the binder after winding. If a number of different forms or mandrels are to be employed, the means for achieving this temperature control must necessarily be rather elaborate.
  • Another object of this invention is the provision of a process for manufacturing filament wound hollow ele- 3,2%,345 Patented ug. Si, 1965 ments which utilizes relatively simple, though highly fiexible equipment.
  • Still another object of this invention is the provision of such a process wherein the equipment required is of a size and nature that is easily portable, thereby rendering on site construction of very large filament wound tanks economically feasible.
  • Still a further object of this invent-ion is to provide a yfilament wound hollow element which includes an inner skin or liner of a substantially different material, and a method for producing this article.
  • FIGURE l is a perspective view showing a mandrel and the initial wind pattern according to the practice of -this invention.
  • FGURE 2 is a side elevational view showing the first unit of a cylinder wound according to this invention, partially broken away.
  • FEGURE 3 is a View similar to FIGURE 2 showing a fully wound second unit in place.
  • FIGURE 4 is a View similar to FIGUR-E 2 showing a 4completed product 4made according to the process of this invention ready for removal.
  • FIGURE 5 is a side elevational View of a form or mandrel showing a bottom closure in cross section positioned thereon.

  • FGURE l() is a view similar to FIGURE 9 showing a plurality of inner skin section joined according to the teachings of this invention.
  • FIGURE l1 is a side elevational view showing a filament wound about the inner skin shown in FIGURE 10.
  • FGURE 12 is a showing of a modification of this invention, partly in side elevation and partly in cross section.
  • a unit length hollow cylinder is formed by a filament winding or other suitable process about an open ended form or mandrel.
  • This unit cylinder is then hardened, and slid or moved along the mandrel by a distance less than the unit length.
  • a second length of hollow cylinder is formed about the mandrel and overlapping the inboard end portion of the first unit cylinder.
  • the method of this invention may be used to produce an interlock between each of the unit cylinders, so that as the process is continued, a hollow element of any desired length may be fabricated. Even though the method of this invention is extremely useful in forming hollow elements of large sizes, the form or mandrel and other winding equipment may be of a relatively small size which need not be reset or adjusted to accommodate varying length requirements.
  • FIG- URE l shows a form or mandrel l, secured to and adapted to rotate about an axle 2.
  • axle i?. is connected to a suitable source of driving power, and that the interconnection may be made through various gears and the like so that any desired mandrel speed may be attained.
  • each unit cylinder is formed by winding a lament onto the form Si in a helical pattern.
  • the helical pattern consists of an outgoing helix beginning at the point 3 and going through the points 3u, 3b, 3c and 3d and ending at the point 3e. Between the points 3e and 4 there is a dwell, or a portion where the filament is wound in a plane perpendicular to the axis of rotation or" the form l. Beginning at the point 4 there is a return helix which is of equal helical angle, but opposite in direction to the outgoing helix 3, 3e.
  • the return helix begins at the point 4, crosses the points 4a, 4b, and llc, and ends at the point dd. Once again there is a dwell between the points ld and 5.
  • a second helical pattern or more specilically, the outgoing helix of a second helical pattern is begun.
  • the point 5 lies on the same circle of the cylinder as the point 3, and that it is substantially adjacent thereto. This will mean that both the outgoing and return helixes of each subsequent pattern will lie substantially alongside the outgoing and return helixes respectively of the immediately preceding helical pattern.
  • the lanient pattern may be in the form of a closed helix in which consecutive convolutions lie immediately adjacent each other, or may even be random wound.
  • the mandrel or form il rotates in a fixed position, while the lament is fed from a feeder mechanism which reciprocates in a path parallel to the axis of the form.
  • the feeder mechanism can be maintained stationary while the form itself is reciprocated during its rotation.
  • the binder sets or solidities, the result is a cylinder held rigid by the binder, but reinforced and given high tensile strength by the encased ilament.
  • this unit must be released from the mandrel by any appropriate means.
  • this release may be accomplished in several ways.
  • the form or mandrel may be precoated with a parting agent prior to the helical winding. The presence of the parting agent permits the unit cylinder under the application of force to be slid along the form or mandrel.
  • the form or mandrel may be made collapsiblev or at least partly collapsible. After the first unit cylinder has hardened, the mandrel may be collapsed thereby releasing the inished cylinder.
  • a second unit cylinder is wound about the t mandrel in precisely the same manner described above for the first cylinder, with the outboard end of the second cylinder overlapping the inboard collar 8 of the iirst cylinder.
  • the process just described may be repeated as often as desired (live units are shown) to produce a hollow element of any desired length.
  • the finished lengths leave the mandrel or form l, they must be supported in substantial alignment with the form. This may be accomplished by means of a plurality of supporting rollers, or a crane supported swivel axis.
  • the method of this invention can also be utilized to produce a closed end vessel, as for example a storage tank, as opposed to the type of conduit described above.
  • the rst step would include the development of an appropriate end closure member.
  • the end closure member can be formed by any conventional means. For example, it may be laid up from a plurality of glass mats impregnated with a fiber glass resin, or it may be formed from an entirely ditlerent material, such as steel or the like, by any well known forming process.
  • a preformed bottom or end closure member 10 is placed over the end of the form or mandrel 1.
  • a filament is then wound about the mandrel l in a helical pattern in the manner described above, with the dwell at the open end of the mandrel (3e to 4 in FIGURE l) overlapping the and closure member lil, as at lll. That is, the dwell portion 3x2-#l of the filament will form a chord across the end closure member. As seen in the upper portion of FIG- URE 6 where the wall and end are shown in cross section, the accumulation of those dwell chords will result in a first unit cylinder having an interloclicd base.
  • the inner lining can be formed of a very thin sheet of polypropylene, or even stainless steel.
  • This aspect of the invention may be accomplished b y the modifications shown in FIGURES 8 through ll.
  • the form or mandrel la may be provided with a longitudinal Welding element 13, and a circumferential welding element lll near its outer end.
  • a strip l5 of the desired liner material (the width of which is substantially equal to the unit length) is wound about the mandrel with an overlapping longitudinal seam 16.
  • the longitudinal edges of the strip l5 are then joined in the area of the overlap f6 by means of welding element i3 in the mandrel.
  • welding element i3 in the mandrel.
  • the welding element will be of a type adapted to accommodate the liner material being used. That is, if the liner is to be constructed of stainless steel, the welding element would be an ordinary electric weldintT circuit; and if the liner material is polypropylene, the welding element can be a heat pressure bar.
  • the unit length liner cylinder thus formed is ⁇ then slid along the mand-rel la a distance less than one unit length as described above.
  • a subsequent strip of liner material a may be wound about the mandrel, circtunferentially overlapping the previously formed liner cylinder as at 17, and having a longitudinal overlapping seam 15a.
  • the longitudinal Welding element i3 then serves to join the longitudinal edges of the layer .l5-idc, and the circumferential welding element ld serves to interlock the adjacent liner cylinders.
  • the liner shell may be covered with a filament wound wall by the modular or sectional process of this invention. That is, as each liner section is formed, it is covered with a unit length filament wound wall, offset slightly with respect to the liner. By virtue of the odset, subsequent liner sections can overlap the preceding liner section, while the filament windings overlap and interlock as described above. Or, if desired, the entire liner shell may be cornpleted to the desired length, and then overwound with a single continuous helical pattern as shown in FIGURE ll.
  • the form will be made up of a plurality of individual and relatively small panels which may be secured together and braced by any appropriate means, so that the resulting structure is readily collapsible and removable from a iinished vessel.
  • the construction of the form does not as such, form a part of this invention, and hence its details are neither shown nor described. With reference to RG.
  • the form and vessel being produced remain stationary, while the winding and feeding mechanism are made to rotate thereabout. As illustrated in FIG. l2, this requires only a suitable pair of tracks 2l which circumferentially surround the form Ztl.
  • a carriage 22 provided with the wheels 23 is adapted to ride along the tracks 21 and will be caused to rotate around the form 20 at a given speed.
  • the carriage 22 carries a column 24 mounted for vertically reciprocating movement.
  • the column 2d includes the feeder or pay out means from which is drawn a lilament strand 25 which is wound about the form as the carriage goes along the track 2i.
  • the unit length hollow cylinders may be wound as indicated in FIGS. l through 4. This will produce the upper collars 26 to 26g inclusive and the lower collars 27' to 27g inclusive. As was described above, the upper collar (26a-26g) of each subsequently wound unit length cylinder will overlap the lower collar (27-2'7f) of the immediately preceding unit cylinder.
  • a bottom 2S may be laid up or formed from suitable material as described earlier, and is set in the proper location on the ground or floor, where the completed vessel is to ybe used.
  • a mast 29 is set in the center of the bottom 28 and is supported by means of the guy lines 30.
  • a cover 31 can be placed over the guy lines for outdoor construction.
  • the mast Z9 may be sectional in design so that as the construction proceeds, additional mast sections may be added, until the vessel is completed.
  • a form 2@ is then set up above the base 28, and may be braced to the mast 29 is desired.
  • a set of tracks 2l are then laid about the circumference of the base Z8.
  • a rst unit cylinder is then formed about the form 2li and in the case of a plastic reinforced vessel, the plastic binder is then solidified.
  • the first formed unit cylinder is the uppermost unit shown in FIG. l2, and includes the collars 26 and 27. It will of course be understood that this unit was wound in the position indicated for the unit having the collars 26g and 27g.
  • a roof 32 is added at this time. It may be secured to the top of the first unit cylinder by any suitable means, including bolts, welding or even an overlapping filament wind.
  • a suitable block and tackle arrangement 33 will then be secured to the apex of the roof 32, and may be used to raise the first formed cylinder slightly less than one unit length. It should be understood that in order to easily accomplish this hoisting operation, it is preferably to slightly collapse the form 2d, to release the cylinder therefrom.
  • the form 2li may be returned to its original size and configuration, and a second section wound thereabout, in the same manner as described above, and overlapping the lower collar 27 ofthe first unit. By alternately raising each successive segment, and thereafter overlapping the subsequent winding, any desired height may be obtained.
  • the form 2li and its braces may be disassembled and removed; the entire structure is then lowered back upon the base 28, and securely fastened thereto, and the mast 29 is removed.
